Purpose
To evaluate the effectiveness and safety of minimally invasive distal intrinsic release
and extensor tenolysis combined with percutaneous release of proximal and distal interphalangeal
joint collateral ligaments.
Methods
The procedures were performed on 5 cadaveric upper extremity specimens, followed by
a full anatomical dissection to assess completeness of the targeted releases and any
damage to surrounding structures.
Results
Complete distal intrinsic release, dorsal capsule release, and distal interphalangeal
collateral ligament release was performed on all specimens. We achieved complete release
of all proximal interphalangeal joint collateral ligaments in 38 of 40 specimens (95%).
We noted damage to nontargeted structures in 2 instances (5%).
Conclusions
Minimally invasive and percutaneous techniques can effectively release several structures
known to cause finger stiffness with minimal damage to surrounding structures.
Clinical relevance
If similar results are seen in clinical trials, this could be a quick and easy way
to increase the mobility of a stiff finger with potentially minimal morbidity.
